   Brain monitor — the agent-loop deep view, embedded in the Agent page (the
   .agent-brain layer carries positioning; this file owns the monitor's own
   layout, including clearing the docked agent panel). Structural chrome rides
   the app tokens (--panel, --hairline, --text, --muted); the functional colors
   below are the monitor's own: phase identities for the loop (look/think/act),
   a series blue for data marks, and a fixed status set — all steps validated
